What is Merge PDF?

Merge PDF combines multiple PDF files into a single document in any order you choose — no desktop software required. Upload your files, drag them into the right sequence, and download a single merged PDF in seconds.

Useful for combining reports, invoices, contracts, or any set of documents you want to send or archive as one file. All processing is done server-side; files are discarded immediately after the merged PDF is returned to you.

Common Use Cases

  • Combining monthly reports into a single PDF for distribution
  • Merging invoice and receipt PDFs for accounting records
  • Joining scanned pages into one continuous document
  • Combining contract sections before sending for signature
  • Assembling a multi-page portfolio from separate files

How to Use Merge PDF

  1. Upload two or more PDF files using the file picker.
  2. Drag the files to set the order they should appear in the final document.
  3. Click Merge and download the combined PDF when it is ready.

FAQ

Are my PDF files stored on the server?

No. Files are processed in memory on the server and discarded immediately after the merged PDF is returned to you. They are never saved to disk.

How many PDF files can I merge at once?

You can merge multiple files in one go. For very large files or a large number of documents, processing time may increase slightly.

Will the merged PDF preserve bookmarks and links?

Internal links and basic structure are preserved. Complex bookmarks or interactive form fields may vary depending on the source files.

Can I change the order of files after uploading?

Yes. After uploading, use the up and down arrow buttons next to each file to move it to the position you want before merging.

Does it work on mobile?

Yes. The tool works in any modern mobile browser — you can pick files from your phone's storage or cloud drive.

Is there a file size limit for merging PDFs?

Very large PDFs (100 MB+) may take longer to process. For typical documents up to a few dozen pages, the merge completes in seconds.
